# 3DD13005ND66F

**Changjing** · Bipolar (BJT) · TO-220F-3

3DD13005ND66F from Changjing, in a TO-220F-3. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | BASE | input | Base terminal of the NPN transistor; the datasheet rates the emitter-base voltage VEBO at 9 V maximum. |
| 2 | COLLECTOR | passive | Collector terminal of the NPN transistor; the datasheet rates VCBO at 700 V, VCEO at 420 V and continuous collector current IC at 4 A. |
| 3 | EMITTER | passive | Emitter terminal of the NPN transistor; the emitter-base limit VEBO is 9 V and the collector-emitter limit VCEO is 420 V. |
